WINDMILL.

SPECIFICATION forming part of Letters Patent No. 389,670, datedSeptember 18, 1888.

Application filed November 14, 1887. Serial No. 255,100. (No model.)Patented in Norway February 10, 18:5; in Denmark July 16, 1885, No. 182,and in Germany March 18, 1886, No. 34,709.

To all whom it may concern.-

Be it known that I, MARCUS J. STRoEM' ing in Brookings county, Territoryof Dakota,

have invented a new and Improved \Vindmill, (for which I have obtained apatent in Norway, dated February 10, 1885; in Denmark, dated July 16,1885, No. 182, and in Germany, dated March 18, 1886, No. 34,709,) ofwhich the following isafull, clear, and exact description.

The object of my invention is to provide a new and improved windmillwhich is simple and durable in construction, very powerful in operation,and self-regulating.

. The invention consists of turbine windwheels of special constructionand secured to the main driving-shaft.

The invention also consists of the construction and arrangement ofcertain parts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in'which similar letters of reference indicatecorresponding parts in all the figures.

. Figure 1 is a side elevation of my improvement. Fig. 2 is an enlargedsectional plan view of the wind-wheel on the line a: x of Fig. 1, andFig. 3 is a sectional plan view of my improvement on the line y y ofFig. 1.

On a suitably constructed frame, A, is mounted the verticaldriving-shaft B,provided with a belt-pulley, O, or chain-pulley 0,connected by belts or chains, respectively, with suitable machinery tobedrivcn, On the upper end of the shaft B is secured a wind-wheel, D,consisting of one or more turbines, E E E, &o., placed one above theother, and each provided with a top and bottom disk F, between which areheld the curved blades G, forming orifices for the entrance and exit ofthe wind, and channels through the wheel. Each blade G is provided witha curved part, G, continuing into a semicircular part, G whichapproaches the center of the disk and terminates in a straight part, Gextending outward to the edges of the disks F. Thus, the wind strikingthe wind-wheel in the direction, say,of the arrow a, exerts its pressureagainst the pocket formed by the curved part G of the blade G, andthereby turns the windwheel in the direction of the arrow [1 The wind,continuing onward from the curved part G of the plate G, is partlydeflected to the next following plate G in the direction of the arrow 0,and in passing out of the wheel strikes against the curved part G ofsaid plate, thus assisting in the rotary motion imparted in thedirection of the arrow b. Part of the wind also passes from the pocketof the part G of the first blade G in the direction of the arrow d tothe third pocket formed by the part G of the third plate, and alsoassists, before passing out of the wheel, in imparting rotary motion inthe direction of the arrow 1) to the wind-wheel D.

The turbines E, E, and E are arranged in such a manner that the outeredges of the parts G and G of each blade G break joints, asillustratedin Fig. 1, so that the wind at all times, from whatever direction itcomes, acts with full force against the wheel D-that is, the wind onentering the orifices, as well as on leaving the same, imparts motion tothe wind-wheel D, thereby turning the main shaft B.

The wind-whee1 D can be covered up wholly or partly by a casing, H,provided with lugs H, held on guides I, secured vertically to the mainframe A. A Ushaped downwardly-extending rod,J, is secured by its ends tothe lower end of the casing H and is provided in its vmiddle with acollar, J, through which passes loosely the main shaft B. On the collaroperate the forked ends of the lever K, fulcrumed at K to the main frameA, and provided near its outer end with a weight, K A link, L, ispivotally connected near the fulcrumed point of said lever K, and alsoconnects with the second lever, N, fulcrumed at N to the main frame A,and carrying on one outer end a weighted lever, N, and on its in ner endbeing provided with a fork, N engaging a collar, 0, of a governor, O, ofany approved construction, and secured by its collar 0 to the main shaftB. When the latter turns 9 5 beyond the normal speed, the governor-ballsfly outward and raise the collar 0, so that the forked end N of thelever N swings upward and its outer end swings downward, therebyexerting a downward pull on the outer end of the lever K, and thusimparting a swing to the same, so that its inner end moves upward andcarries with it the U shaped rod J, connected with the casing H, so thatthe latter slides over the wind-wheel D a certain distance, aeeording tothe movement of the governor-balls. Part of the wind-wheel or the entirewindwheel is thus covered up and the wind exerts its force only 011 partof the wheel, thereby decreasing its speed until the main shaft B againruns at a normal speed, when the governorballs have moved to theirformer position, thereby removing the casing H again below the wheel D,as illustrated in Fig. 1.

It will be seen that by my improved windwheel I utilize the full forceof the wind, regulate the speed of the shaft B automatically, and thewind can always act from whatever direction it blows without theshifting of vanes and other devices usually employed in windmills. Inorder to present as few obstructions as possible to the wind forrotating the wind wheel D, I prefer to construct the upper part ottheframe A with metallic rods A,supporting the wooden top A which carriesthe uppermost bearing for the main shaft B.

IIaving thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A turbine wind-wheel consisting of top andbottom plates and a series of spaced and independent blades arrangedbetween the said plates, each blade extending inwardly from the 1periphery toward the center and then curved outwardly to theperipheryagain,substantially as described.

2. A turbine wind-wheel consisting of top and bottom plates 1 and thespaced and independent blades G,each formed with the curved part G,thesemicircular partG",a11d the curved part G, substantially as hereinshown and described.

3. In a windmill, the combination, with the main shaft,a wind-wheelmounted thereon, and a sliding casing for partially or wholly coveringthe wheel, of a weighted lever engaging a collar carried by the casing,a governor on the main shalt, and a second weighted lever ongaging acollarot the governor and connected to the firstnamed weightedlever,suhstantially U as herein shown and described.

t. In a windmill, the combination, with the main shaft 13 and thewind-wheels l) EEfland the governor O 011 the said shaft, of the slidingcasing .l'I, provided with a downwardlyextending arm, J. the pivotedweighted lever K, engaging a collar on the said arm, a second pivotedand weighted lever, N, engaging a collarot the governor, and the link L,pivoted to the said levers K N, suhstantiallyas herein shown anddescribed.
